* If an undefined weak symbol is not resolved to a defined symbol at link time,
the linker can choose whether to promote the symbol to a dynamic symbol or not.
If promoted, the weak symbol has another chance to be resolved to a defined
symbol at load time. Otherwise, it is resolved to address 0 at link time.
Previously, mold always resolved remaining undefined weak symbols in an
executable to address 0 at link time. Now, you can instruct the linker to
promote them to dynamic symbols using -z dynamic-undefined-weak. (1822e47)
* [x86-64] The relocation types
R_X86_64_CODE_4_{GOTPCRELX,GOTTPOFF,GOTPC32_TLSDESC} and
R_X86_64_CODE_6_GOTTPOFF are now supported. These relocations are for Intel APX
(Advanced Performance Extensions), which extends the number of general-purpose
registers from 16 to 32. (83152ac, a17202d)
* [ARM32] The R_ARM_THM_JUMP8 relocation type is now supported. (1fbbcec)
* [ARM32] Previously, the .ARM.exidx section (which contains exception-handling
records) was not subject to garbage collection, even when --gc-sections was
specified. This prevented all functions from being garbage-collected, as they
were referenced by exception-handling records. Now, mold correctly
garbage-collects unused .ARM.exidx records and functions. (16f7599)
* Previously, --compress-debug-sections was ignored if --separate-debug-file was
specified. Now, mold compresses debug information sections even when they are in
a separate debug file. (bab7dd1)
